Abstract
P277 Z-99 CORRECTION OF TRANSMISSION DISTORTIONS ON CMP-GATHERS Summary JESPER SPETZLER Dept. of Geotechnology TU-Delft The Netherlands Small-scale structures in the overburden are responsible for transmission distortions on reflection data on the same order as or even larger than the reflection response at reservoir level. I present a new methodology to correct for overburden transmission distortions on reflection data. The correction method is applied on CMP-gathers in a synthetic experiment with a gas-chimney above a leaking reservoir. Introduction Overburden structures that can have a significant effect on the transmission response of a reflected wave field are gas chimneys fault systems
